Subject: [PATCH v2 2/5] sha1_file.c: keep a good name for "unknown" hash_algos[UNKNOWN]

From: Nguyễn Thái Ngọc Duy <[email-masked]>
Date: Sat, 24 Feb 2018 10:34:26 +0700

This is mostly for displaying the hash algorithm name when we report
errors. Printing "unknown" with '%s' is much better than '(null)' in
glibc printf version (and probably could crash if other implementations
do not check for NULL pointer)
